Compact

Instructions

Write a function Compact that takes a pointer to a slice of strings as the argument. This function must:

  • Return the number of elements with non-nil.

  • Compact, i.e., delete the elements with nil in the slice.

Expected functions

func Compact(ptr *[]string) int {

}

Usage

Here is a possible program to test your function :

package main

import (
       "fmt"

       piscine ".."
)

const N = 6

func main() {
	arr := make([]string, N)
	arr[0] = "a"
	arr[2] = "b"
	arr[4] = "c"

	for _, v := range arr {
		fmt.Println(v)
	}

	fmt.Println("Size after compacting:", piscine.Compact(&arr))

	for _, v := range arr {
		fmt.Println(v)
	}
}

And its output :

student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
a

b

c

Size after compacting: 3
a
b
c
student@ubuntu:~/[[ROOT]]/test$
